Set up maintenance-free container gardening with the Supreme Fiberglass Flower Boxes. This 24" planter box is ideal for small front windows or the wall adjacent to a patio. Durable construction out of fiberglass makes this a weather resistant container, unfazed by hot or cold, and without susceptibility to rot and mildew. Smooth finishing throughout also makes fiberglass planters easy to rinse out as needed for re-potting or storage.

Each 24" fiberglass planter comes with (2) stainless steel wall brackets and matching bolts, a high-strength extruded construction, and a custom-fitted drainage mat. This system for runoff pushes excess water over the bottom of the container to end-cap openings. Funneling moisture out discourages over-watering while allowing airflow to plant roots for healthier container arrangements.

Supreme Fiberglass Window Boxes in Slate Grey are just one of many color options. This product is also customizable in sizes measuring up to 14' long; please call toll free for details.

Bolts are included, but if you are mounting the box to a stone/brick home, you will need to purchase lag shields separately.
